IMPROVEMENT IN MACHINES FOR s Ewmc Boo-rs ANDSHOES}.

Specification forming part of Letters Patent No. l2,4.- 20 ,dated SeptemberlQ, [1376; application tiled a I May 27,1875.

Be it known that I, JOHN OUTLAN, a sub ject of the Queen of Great Britain, and now a resident of Camden, in the county of (Jamden and State of New Jersey, have invented certain Improvements in Machines for Sewing Boots and Shoes, of which the following is a specification, reference being had to the accompanying drawings, in which like letters represent like parts. w

My invention relates, first, to the construction and mounting of two vertical convex feedwheels together to sustain the shoe to be sewed upon ahorizontal shaft having its bearings in the frame of the machine, the

outer one of said feed-wheels being rigidly fixed upon the outer end of the shaft, while the other is loose upon and has a limited amount of play along the length of the shaft, and yields from the direction of the outer wheel elastically against the force of a spiral spring seated on the shaft.

This inner feed-wheel is recessed upon its outer face, to afford working room for the thread, thread-carrier, and needle, as herein-,

after more fully described.

Secondly, to constructing a thread-carrier with such form, and mounting it upon a bearing in such a manner, that its upper end will carry the thread in its upper end within the recess in the feed-wheel, as hereinbefore mentioned, and have two separate and distinct movements caused by the action of other devices upon its lower end, as hereinafter more fully described.-

Thirdly, to the combination of two other shafts mounted in the frame, one above the other, and both below the feed-wheel shaft, before mentioned, and their cams and other auxiliary partswhich cooperate to produce the two separate movements of the threadcarrier, hereiubefore mentioned.

Fourthly, to a combination of devices by means of which the needle, when it has made itsdownward thrust through the work, and has caught the thread below it upon its barb, is made to revolve upon its vertical axis halfway around, in order that the barb may not catch the loop in returning above the work again, and then to revolve back to its origi nal position before making another downward thrust.

Fifthly, to a combination of devices, by A which the vertical presser is operated in such and at the instant of the upward or return movement of the needle-bar it is grasped and held firmly in position until the stitch is pulled in, when it is released again, as hereinafter more fully described. I

Sixthly, to a combination of parts constituting a frame swinging horizontally for the convenient support of the work while being sewed, and holding it against the feed-wheel, ashereinafter more fully described.

In the accompanying drawings, Figure 1 represents a perspective view of a] machine embodying my improvements Fig. 2, a front" elevation'of the upper part of the same; Fig.

3, a side elevation thereof; Fig. I, a side elef vation of the swinging frame, and a central longitudional vertical section of the feedwheels, shafts, and other accessory parts; and

Figs, 5, 6, 7, and 8 are detail views of devices embraced in the same.

The letter A, wherever it occurs, indicates the frame of the machine. Motion is impart ed to all the operative parts by means of a band over pulley F on themain shaft '13, which imparts motion in the same direction to the lower shaft K by means of the pinions E and I and the intermediate gear G; and, by means of the cam-slot in the face of cam-wheel i, and the connecting-rod k, provided with wrist-pin 2", as shown in Fig. 3, the shaft B by every revolution turns shaft E a few degrees, and with it the feed-wheels, and thus affords the feed-motion required, and the ratchet-wheel b and its pawl on shaftE prevent retrograde motion of that shaft.

The spiral spring 0, seatedvon the shaft E between the hub of feed-wheel N and the frame, presses thatwheel in the direction of feed-wheel O. The pin 6 in the shaft E prevents the feed-wheel from turning upon it,

and the slot 0 in the'hub ofthefeed-wheel N allows the playupon-the shaft lbefore mentioned.

In Fig. 4 is shown an annular recess in the in terior'of feed-wheel N, extending around port W, and is hinged theretohymea-ns of a pin,'as shown, and the body of that support extendsjnto ;a recess within th-e outer endjof shaft S, which has'its hearings in the frame, and a spiral spring, 8, seated within the recess presses the lower end of the carrier T, which is provided'with a friction-rollen out against the cam-wheel P, and so when the cam revolves the lower end of the carrier is vibrated inwardly and outwardly by the joint action of the spring and' cam, and the upper end'is given one of the movementsrequired. k

The/second or edgewise movement is given tojthe thread-carrier by means of the shaft S,

which supports'its bearingW, and which is" rocked a'few degrees" upon its axis by every revolution of the shaft K by means of the bar t, which" at its upper end- 'isrigidly attached to shaft S, and at its lower endis provided with wrist-'pin't which works in a suitable cam-slot in the face of cam-wheel R, which is fixed on shaft K. 1%

The top;.endof the carrier is bent over in the direction of the front of the machine, so as to form a right angle with its side, and that tip thus formed is pierced with a vertical hole for the thread, which is passed up from the spool below.

Now, when a stitch, is to be madethe' needle" is thrust downthrough the leather, and the carrier makes its outward movement, and drawsthe thread past the'needle, above its notch and barb, and then makes its edgewise movement at right angles with the line of the first, and wraps the'thread partly around the needle, which, then, upon its upward or return movement, catches the thread on its barb, and p'u-lls'it up the stitch.

'The needle-bar B, bearing the needle, receives its vertical reciprocating motion from the shaft B by means of a cam, as shown, in the'usual way.- v

In order to oscillate the needle-bar upon its vertical-axis,=for the purpose hereinbefore stated, it is" inclosed within a toothedwheel, so that it cannot turnin the wheel, but is.

T fiee to reciprocate vertically therein; and a toothed sector','n, is pivoted on a projection, a, of the frame, as shown, to mesh with toothed wheel r, and the sector is provided with a wrist-pin, t which is made to work in a suitably-formed slot in cam M on the shaft B, and these parts are so arranged, with respect to each other', that the oscillation shall begin and end exactly when desired, with respect to the vertical action of the needle-bar.

The devices for operating the presser-foot O through the leather and forms B, while the other end of the lever 07 is pronzidednith a hollow vertical arm or elbow, 01 which loosely incloses the upper portion of the pr. seer-bar 0,-which is held in its vertical positionby the 'arlnsea'nd a of the frame,

d holds'thefoot of thebar; down upon the work with an elastic pressure that will prevent -the--feed-movement; but just before the upthe rear end d of spring-lever d, and causes theforwardend of that lever, by its hollow the work, against the return movement of the needle until the stitc releases it again,- 7

The grasping action of the hollow elbow 'd 'upon the upperpo'rtion of the presser-bar O is due tothe'change in the direction of the elbow in respectto the presserbar, which 'cau'ses'a" pinching action between I them. The tension of the thread is regulated in Fig. 3, andneed not' be further'described,

A side vie'w'of'the swinging frame hereinbe-- fore mentioned is presented in Fig, 4. The bar U has one end inserted in the last'inthe' shoe u, and uponthe bar are seated two spiral;

with vertical bar J, which, in its turn, is-ad-' ju'stably connected with the horizontal crane- By means of the adjustable connections shown between the bar U and the horizontal; bar, the inclination of'the bar U may be I changed, as may be required, to'suit'difterent I kinds of work.
